متن کاملA Ubiquitin Stress Response Induces Altered Proteasome Composition
Ubiquitin-dependent protein degradation is essential for cells to survive many environmental stresses. Thus, it may be necessary to buffer ubiquitin and proteasome pools against fluctuation. Proteasome levels are tightly regulated, and proteasome deficiency stimulates a stress response. Here we report a novel pathway of cellular response to ubiquitin depletion. Unlike proteasome stress, ubiquit...
متن کاملDysregulation of the ubiquitin-proteasome system in human carotid atherosclerosis.
OBJECTIVE The ubiquitin-proteasome system is the principal degradation route of intracellular and oxidized proteins, thus regulating many cellular processes conceivably important for atherosclerosis. The aim of this study was to evaluate the activity of ubiquitin-proteasome system in human carotid artery plaques in relation to oxidative stress and clinical manifestation. METHODS AND RESULTS I...

Background: The ubiquitin-proteasome system (UPS) plays a crucial role in regulating the levels and functions of a large number of proteins in the cell, which are important for cancer cell growth and survival. The proteasome is highly activated in B-cell precursor acute lymphoblastic leukemia (BCP-ALL), which is the most common malignancy in children. The attempt to inhibit proteasome as a ther...
متن کاملDysfunction of the ubiquitin-proteasome system in atherosclerotic cardiovascular disease.
The ubiquitin-proteasome system (UPS) is an integral part of the protein metabolism and protein quality control in eukaryotic cells. It is involved in a number of biological processes of significance for vascular biology and pathology such as oxidative stress, inflammation, foam cell formation, and apoptosis. This review summarizes both indirect and direct lines of evidence for a role of the UP...
متن کاملA free radical-generating system regulates AβPP metabolism/processing: involvement of the ubiquitin/proteasome and autophagy/lysosome pathways.
Oxidative stress is an early event in the pathogenesis of Alzheimer's disease (AD). We previously reported that, in SK-N-MC cells, the xanthine/xanthine oxidase (X-XOD) free radical generating system regulates the metabolism/processing of the amyloid-β protein precursor (AβPP). Oxidative stress alters the two main cellular proteolytic machineries, the ubiquitin/proteasome (UPS) and the autophag...
